RESUMO

The Las Vegas valley and Clark County have a long history of flooding and flood damage. The Las Vegas valley is unique in that it is surrounded by mountain ranges with steep slopes that empty onto alluvial surfaces. Ultimately stormwater runoff has to pass through areas that are being rapidly urbanized. The steep slopes and unpredictable flow paths on the alluvial fan surfaces compound the flooding and engineering problems facing developers and the Clark County Regional Flood Control District. The problems also include the possibility of flood waters transporting tremendous amounts of debris and sediment. In the urbanized areas of the Las Vegas valley, development and pavement of the desert increases direct runoff and speeds its flow. It is difficult to convince newcomers that the threat of severe flooding exists in a desert region that receives only 4 inches of rain annually. More recently, since the 1960s, the Las Vegas valley has experienced unprecedented, rapid growth

RESUMO

In 1987, the Louisville and Jefferson County Metropolitan Sewer District (MSD) prepared master plans for the 11 watersheds in Jefferson County, Kentucky. The purpose of the master planning effort was to establish the present and expected future hydrologic and hydraulic characteristics of the creeks and major tributaries utilizing a consistent methodology (HEC-1 for hydrology and HEC-2 for hydraulics). The process development and its testing were conducted for a pilot basin, the Cedar Creek Watershed, located in southeast Jefferson County. The objectives for the Pilot Basin Study (PBS) were derived from the need to utilize the GIS system to develop solutions for identified flooding problems

RESUMO

In urbanized areas, where development is essentially uniform with respect to drainage to streets, the flood damage potential may be related to the flood depth in the adjacent street section. For a particular street geometric cross-section, a given flood depth may be correlated to different levels of flood damage potential depending upon the development of contiguous land areas. The Cost-to-Benefit-Index (CBI) method is a graphical means to communicate important information regarding master planning prioritization of flood control system elements targeted for improvement. Using the CBI approach, decisions can be made regarding which system reach or system elements may be ranked as having the highest priority in scheduling construction. Additionally, a CBI map aids in communicating to the public the relative importance of any particular element with respect to the overall master plan
